I decided to re-install Gentoo to move from 32 to 64 bit. But now, the root file system is getting mounted read only. I can manually re-mount read-write at the end of the boot process, but I'd prefer a proper solution.

The error seems to come when starting the root service, and I get the error:

"root filesystem could not be mounted read/write"

The stage 3 that I installed had openrc-0.11.8. Downgrading to 0.11.6 made no difference

In my kernel config (gentoo-sources-3.7.1) I have

# CONFIG_DEVTMPFS is not set
CONFIG_TMPFS=y
CONFIG_TMPFS_POSIX_ACL=y
CONFIG_TMPFS_XATTR=y

I tried initially with CONFIG_DEVTMPFS=y but it didn't work either.

Re-installing udev not helped either._________________Things you might say if you never took Physics: "I'm overweight even though I don't overeat." - Neil deGrasse Tyson

This might not solve your problem immediately, but these should be set: CONFIG_DEVTMPFS=y and CONFIG_DEVTMPFS_MOUNT=y

OK, I've re-set them, not made any difference though, and my old 32-bit install doesn't have this set._________________Things you might say if you never took Physics: "I'm overweight even though I don't overeat." - Neil deGrasse Tyson
